The “w-hai” recreational outdoor brand was born in 2007 as a new fashion outdoor brand that combines the development, production and sale of leisure outdoors. W-hai has tightened the quality of the product to ensure that each product meets the technical requirements of the life-saving series of the six and seven astronauts, and that even in an environment as bad as outer space, you can enjoy leisure outdoors. The main types of leisure outdoors that we're dealing with are clothing, footwear, bags and outdoors. The full range of “w-hai” recreational fashion outdoors is provided to users with a full range of leisure fashion, high performance, and recreational fashion sports equipment from the top to the foot. The “w-hai” climber shoes bring together the 88-year experience of the twin-star group in making shoes, integrated tyre manufacturing techniques, 100 per cent of the soles using the technology and self-owned process of full steel silk-mounted heavy meridian tyres, with incomparable ground-capability and good millability, which is 7-13 times more resistant, torn apart and resistant than ordinary climbing shoes, with friction coefficient accuracy controlled between 15 and 2 per cent. The “w-hai” series of hiking shoes brings surprises to fashioners who love recreational campaigns, outdoor sports, field sports and adventures. The “w-hai” leisure clothing has several dual-star proprietary technologies. The entire “w-hai” series uses a “high standard new product - micro-porous multi-functional gas-respiration material” exclusive to the twin-star group, along with a proprietary technical product - a multi-purpose foundational water treatment agent that reduces “tribenzo” and “polyze” from “w-hai” to a truly green, environmentally friendly product. The “w-hai” series has a unique backpack system, loading system and external hanger system based on human engineering and mechanics. The “w-hai” series of tents, sleeping bags, cookers, lighting systems, etc., and ykk, donnover's better quality accessories, provide outdoor sports fans with a genuine “outdoor armor”.
